Modem Reset during TCP CLient Connection

Legacy Open AT
1

Dear Master…

I am using wavecom Q24 plus as TCP client, using WIP Soft plugin. And I create TCP server application in my PC.

AT+WIPCFG=1 
OK 

//start IP stack 
AT+WIPBR=1,6 
OK 
//open GPRS bearer 
AT+WIPBR=2,6,11,”APN name” 
OK 
//set APN name of GPRS bearer 
AT+WIPBR=2,6,0,”user name” 
OK 
//set user name 
AT+WIPBR=2,6,1,”passwd” 
OK 
//set password 
AT+WIPBR=4,6,0 
OK 
//start GPRS bearer 
AT+WIPCREATE=2,1,”ip 
addr”,80 
//create a TCP client towards peer IP device 
@ “ip //addr”, port 80. 
OK  //all parameters and iP stack behavior are 
OK. 
+WIPREADY: 2,1   //unsolicited: the TCP client socket is 
connected //to the peer 
AT+WIPDATA=2,1,1 
CONNECT

After the connection, I can exchange the data with the modem. But after several byte of data the modem send
+WIND = 3, modem reset…

Anyone can help me? Why this can be happen?

Thanks

Hi
Which firmware version are you using?? Does this reset happens only after a certain amount of data is transferred or is it random??

Are you running an application on the device?
